OIL-BURNER.

Specification of Letters Patent.

Patented Aug 27, 1918.

Application filed March 26, 1918. Serial No. 224,811.

T all whom it may concern:

Be it known that I, lVILLIAM l\TALLORY, a citizen of the United States. residing at Topeka. in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Oil-Burners of which the following is a. specification.

This invention relates to oil burners and the object of the invention is to provide a simple and eflicient apparatus by the use of which coal oil or similar fuel will be rapidly and thoroughly vaporized and c011- sumed. A further object of the invention is to provide an oil-burning apparatus which may be also utilized to burn coal, wood, or other solid fuel. The invention also seeks to utilize the heat thus produced in an advantageous manner.

The invention is illustrated in the accompanying drawings and consists in certain novel features which will be hereinafter first fully described and then particularly pointed out in the appended claims, and in the said drawings:

Figure 1 is an elevation of an oil burner embodying my improvements.

Fig. 2 is an enlarged vertical section of the same.

Fig. 3 is an enlarged vertical section of the burner plate and the parts cooperating therewith.

Fig. 4 is a plan view of the burner plate.

Fig. 5 is a detail perspective view of the ignition or ash pan.

Fig. 6 is a detail of a portion of the drum.

Fig. 7 is a view partly in elevation and partly in section showing an arrangement whereby my improved burner may be used in a house heating system.

Fig. 8 is a detail horizontal section on the line 88 of Fig. 7.

Referring more particularly to the drawings, the reference numeral 1 indicates a base or support in which is a door 2 provided with a damper 3 of a well-known type. Upon the base 1 is supported a drum or casing consisting of an outer wall 4 and an inner wall 5 which is constructed with a horizontal annular flange 6 atits lower end in which are openings 7. The said flange 6 is provided at its outer edge with a bead or other form of slight projection 8 which serves to center the outer wall t. The inner wall 5 is provided with a plurality of openings 9 therethrough so that air may reach the coil 10 disposed at the inner side of said wall and supported by brackets 11 on the base 1. A cover 12 is supplied upon the drum and supported upon the upper end of the outer wall t, this cover being provided with an escape fine 13 and with a door 1% providing means for inserting coal, wood or other solid fuel into the device. The coil 10 forms a portion of the vaporizing apparatus and at its lower end is equipped with a nozzle 15 disposed centrally of the base 1. The upper end of the coil is connected with an 011 supply pipe 16 by a coupling 17 which also receives a terminal of an air supply the branch 20 between the pipe 18 and the nozzle 15 as shown. The oil is contained in a tank or reservoir 23 from which the pipe- 16 leads and a cut-off valve 2% is provided in said pipe to control the flow from the tank to the coil. A pipe 25 leads from the top of the air reservoir 19 into the top of the oil tank 23 and a valve 26 is fitted in said pipe to control the flow through the same.

A valve casing 27 is interposed in the nozzle 15 and in the said casing is mounted a needle valve 28 by which the flow of vapor to the burner 29 is controlled, the stem 30 ofthe said valve 28 being elongated so as to project through the base as is clearly shown. The burner plate consists of a central hub 31 secured directly on the lower end of the nozzle 15 and having its lower end closed and constructed to present a conical or tapered deflector 32 which projects somewhat into the lower extremity of the nozzle, as shown clearly in Fig. 3. From the said hub a plurality of arms or tubes 33 radiate to a rim 34c and the bores and hollow passages of the said arms are extended downwardly through the said rim and open through the lower edge of the same, as shown at 35 in Fig. 3. An ash pan or ignition pan 36 is suspended on and below the burner plate and to this end the said ash pan or ignition pan is equipped at diametrically opposite points with radial projections or lugs 37 adapted to be engaged over the hooks 38 formed on the under side of the burner plate as shown and as will be readily understood. A lining or shell 38 is placed within the coil 10' and rests at its lower end upon the burner plate so as to conis flared or curved outwardly so as to pro ectover the shown at 39, and thereby a shield for the coil to prevent coal or wood lodging thereon when being inverted into the fuel basket. To provide a support fo u fuel. a grate 3i) is titted in abate the nozzle 15,

coil as the uel berd off the burner while the pac ie radial arms 53 of the burner p ovn i-Qeans for the ashes o fall through the ash nit formed by the lower portion or the base 1.

The operation is thought to be clear from what has been said. ll? may be stated, however. that when it is desired to burn oil, the val 2G and 94- are opened so that air unre will be admitted to the top of 52S and, by playing upon the surface of the oil in said tank, will force said fuel through the wipe 1.6 into the coil 10. Air mav be admitted to the top of the coil, by opening the valve 21, to min le with the oil and aid in the *apori: ion or the same and. if the oil saould be yery heavy, additional air may be admitted into the noi'r/zle 15 by opening the valve so that: the vapor will be thin and rev-.rlily ignited when it issues from the openings 35 in the burner plate. hen starting a tire, a small quantity of oil is permitted to flow into the pan 36 after which the valv 28 is closed so as to cut off the flow. The oil upon the pan 3G is ignitet and the flame therefrom will play directly on the burner plate so as to heat the same, the result being that the oil which subsequently flows through the plate will be thor cughly vaporized and will be. instantly ig nited when it issues from the burner plate. This initial igniting charge of oil having been consumed, the i opened y alve .20 is again and the vapor ignited at the openings 35, the intensity of the flame being controlled by regulation of the valve 28 as will be readily understood. The flame will rise past the burner plate and play upon the coil it) so that said coil will quickly become heated and the oil flowing through the same will be vaporized so that combustion will be complete. the edge of the burner plate. .rir will be drawn in through the openings 7 and will rise through the drum to minglet flame at the upper edge of the inner wall 5, the shield 39 ser ing also as a defi er-tor to turn the flame toward drum as will be evident. As the air iningles with the flame at the upper end of the drui'n, a-

very hot blue flame will be produced so that. a large quantity of heat will be furnished with a minimum consumption of fuel. The heat may be carried off through the fine 13 to any point of use or the cover 12 may be removed and the heat permitted to dissipate and distribute itself as it emerges from the drum.

in Fig. '7 I hay-e illustrated a mode of utilizing the heat from my burner in a house-heating system. l pon the upper end ol the wall t is placed a hollow wall casing to having openings 4:1 in its lower end through which air may rise to be heated while within the casing and finally pass out through hot air flues -12 to any part of the house. Within the casing is l anged a coil containing water and obviously exposed to the direct action of the heatrising from the burner. The inlet pipe ll and the outpipe of this coil are equipped with "alves 4'3 and a drain l7 may also be pro vided. A water tube gage l8 may be fitted in the coil in the event that it is to be used with a steam generator and a pressure gage l9 and safety valve 50 may also be provided therefor. A fuel feed door 51 may be provided in the top of the drum and an ordinary swinging door 52 may be provided on the "ront of thedrum near the lower end the same to permit reu'ioval of clinkers or and inspection of the flame.

Having thus described the invention, what is claimed as new is:
